SU LKY-PLOW.

SPECIFICATION forming part of Letters Patent No. 239,249, dated March 22, 1881.

Application filed November 5, 1880. (No model.)

Z0 all whom it may concern:

Be it known that I, FRANK A. siding at San Leandro, in the ,county of Alameda and State ot' California, have invented a new and useful Improvement in Sulky or Gang Plows, of which the following is a specification.

My invention relates to the means employed to adjust or change the height of the landwheel of a sulky or gang plow with reference lo the furrow-wheel, as may be required,by the plows running at a greater or less depth.

My invention is illustrated bythe accompanying drawing, in which the figure represents a common gang or sulky plow, with the plows, tongue, and seat removed.

A and A' represent the iron beams to which the plows are attached.

B is an iron bolster, to which the axle O, having the studs or arms D and D', is hinged. The function of the axle O, with its arms D y and D', is to raise and lower the beams A and A' in the usual manner when it is rotated by means of the lever I.

Journaled on one end of the axle U is a hellcrank, E, having a spindle, on which the landwheel K revolves. The said bell-crank E is connected to the lever F by the connectingbar G. The said lever F is pivoted at its lower end to the bolster B, at the point where the axle C, with itsstuds or arms D and D', is

HILL, re-J depth of plowing. l Having thus described my invention,what l attached. The said lever F may be held in any desired position bythe segmental ratchet H. The bell-crank E is moved as may be desired by the lever F through the medium ot' the connecting-bar G, thus raising or lowering the land-wheel K, so that the plows may run at any required depth.

It will be seen that the position of' the said land-wheel K can be quickly changed by the above-described means, while the axle C remains free to rotate, by means ol' the lever l, and raise and lower theplows. In other words, either of the levers F and I may he moved freely the length of its ratchet, while the other is held at a fixed point, thus enabling the driver, without stopping his team or leaving his seat, to adjust his plows to any required claim, and desire to secure by Letters Patent, ls-

The axle C, having the arms D D', and locking-lever I, in combination with the bolster B, carrying beams A A', and also pivoted on said arms, and with the lever F, bell crank E, connecting-link G, and wheel K, all asl'aud for the purpose set forth.
